Peculiarities of radon 222Rn emanation with depth

Soil gas 222Rn concentration in northern Germany and its relationship with geological subsurface structures

“…In the salt dome environment, a potential microbubble ascent would be supported by the Ostwald coefficient K for 222 Rn, which decreases with temperature and salinity increase (Clever, 1985). The role of 226 Ra transport by microbubbles is not completely investigated yet, but some authors reported that 226 Ra is transported mainly by gas flow (Spivak et al, 2008).…”
